What applications would prefer the bipolar junction transistors over the field effect transistor?
bjt is bipolar device whr fet is unipolar....fet is input resistance thts y fet gain is less compared to bjt..... The applications that will prefer bipolar junction transistors to field effect transistors are applications that require fast switching.
Why cmos consume low static power?
CMOS is a dynamic power consumer...whereas BJT consumes power always.... cmos consumes power only while switching from one astate to another state...i.e while switching
Why fet is preferred over the bjt?
Disadvantage:Easy to damage when compared to BJT
What are the advantages and disadvantages of JFET over BJT?
An advantage of JFET is stable high current operation. A disadvantage of JFET is low capacitance. An advantage of BJT is constant voltage operation. A disadvantage of BJT is low thermal conductance.
What are the differences between bi-cmos and cmos technology?
CMOS circuits utilize complementary MOSFETs, i.e; NMOS and PMOS devices together in various patterns to create functional blocks like AND or OR gates. However the problem with these types of CMOS circuits is that they are inherently low power circuits. They cannot handle large currents. So when your block needs to have a large fan out (need to drive a large no of outputs, i.e; more current required) CMOS circuits fail. That is why we use BiCMOS. They are very similar to CMOS circuits except for the BJT(Bipolar Junction Transistor) output stage. BJTs are capable of carrying large currents, hence BiCMOS circuits are used in cases of large current requirements.
Which crystal structure is preferred to fabricate BJT in VLSI technology?
For MOS fabrication, wafers with crystal orientation <100> are used. This helps achieve a lower threshold voltage and for BJT <111> orientation is preferred.
What is the advantage of bistable multivibrator using 555 ic over those made with opamp or bjt?
The advantage is most of the circuit has already been connected up for you and you only have to add a dc power supply and couple of components to set what frequency you want it to work at.
Why bjt is bipolar?
Bjt is bipolar because in bjt the conduction of current is due to the electrons as well as holes
What is the main advantage of an fet transistor over a bjt transistor?
BJT & FET parameters are temperature dependent. In BJT the collector junction resistance decreasing ( collector current increasing) with temperature raise.Due to the highe temperature & current transistor will damage quickly. In FET drain resistance increasing (drain current decreasing ) with increasing temperature.Due to this property it will not damage easily. We can say from the above two statements FET is more temperature stable.FET can use in highe temperature applications.
What are the example current controlled device?
Bipolar junction transistor(BJT)
Why Bicmos technology is not used in microprocessors?
Using BJT technology alone would not make a viable microprocessor, as power consumption and heat dissapation would become problematic. Mixed technology BiCMOS complicates the manufacturing process, increasing the shelf cost of the end product.
What is the difference between BJT and NPN transister?
Mainly there are two types of transistors. They are BJT (Bipolar Junction Transistors) and FET(Field Effect Transisters). In BJT, there are two types called PNP and NPN. Actually NPN means a BJT transister.
Applications of hybrid pi model of bjt?
ApplicationsThe BJT remains a device that excels in some applications, such as discrete circuit design, due to the very wide selection of BJT types available, and because of its high transconductance and output resistance compared to MOSFETs. The BJT is also the choice for demanding analog circuits, especially for very-high-frequencyapplications, such as radio-frequency circuits for wireless systems. Bipolar transistors can be combined with MOSFETs in an integrated circuit by using a BiCMOSprocess of wafer fabrication to create circuits that take advantage of the application strengths of both types of transistor.
